When compiling the project, I get this obscure Exception
Looking for precompiled archives. To disable, use -Dgwt.usearchives=false
Loading archived module: jar:
In my case I had to remove the asm 3.1 from my classpath and there are few jars which has internal dependency on asm 3.1. Which i had to exclude from the dependency in my pom. example:
org.apache.cxf
cxf-rt-frontend-jaxws
2.7.18
asm
asm
There were other jars which has such internal dependency, use maven dependency tree to identify. and exclude asm dependency.
Note: you can even upgrade these jars to higher versions which in fact support higher versions of ASM(>4.0), which should be fine with GWT 2.7 or 2.8
